GAS-HEATING SAD-IRON.

To all whom it may concern:

Be it known that I, CHARLES GUNN, Jr., a citizen of the United States, residing at Mount Royal, in the county of Gloucester and State of New Jersey, have invented certain new and useful Improvements in Gas- Heating Sad-Irons, of which the following is a specification. I

This invention has relation to gas heated irons and it consists in the novel arrange ment of its features as hereinafter described and claimed.

An object of the invention is to provide-an iron of the character indicated of simple structure, the parts being so arranged that.

in the body of the iron is thoroughly and effectually attained. With this object in view the iron is provided with means for mixing air with the gas in the body of the iron, and this mixture consumed whereby the gas is economized and the base of the iron is thoroughly and uniformly heated.

With the above objects in view, the iron comprises a body having a base ofuniform vertical thickness except as hereinafter specified. Walls ascend from the edges of the base and these walls are provided with inner surfaces which are vertical with relation to the inner surface of the base. The walls are provided at their upper portions with openings through which the products of comiron. A cover is hingedly connected with the upper portions of the side walls of the base and means is provided for securing the forward portion of the cover closed over the edge walls of the base. A gas supply tube passes through the rear wall of the body and is screw-threaded into engagement with the forward portion thereof, whereby the said tube is secured and the forward end thereof is closed. This tube is provided at its lower portion and at the opposite sides of its median longitudinal dimension withdownwardly and outwardly disposed apertures. The base of the body is provided at the opposite sides of its median longitudinal dimension with air passages which extend from end to end of the base. Openings communicate with the interior of the body and the upper portions of the said passages. The apertures hereinbefore mentioned are directed toward said openings. The passages are of greater transverse sectional area than the openings.

Specification of Letters Patent.

With these and other objects in view, the invention consists in certain novel features of construction, arrangement and combina tion as will be; hereinafter more fully described and then specifically pointed out in the claims.

In the accompanying drawing, Figure 1 is a top plan view of the iron with parts in section; Fig. 2 is a vertical longitudinal sectional view of the iron Fig. 3 is a transverse sectional view of the iron out on the line 3-3 of Fig. 1; f is a similar view out on the line44 of Fig. 1; and Fig. 5 is a side elevation of the iron.

Corresponding and like partsare referred to in the following description and indicated in all the views of the drawings by the same reference characters.

The body of the iron comprises a base 1 which is of uniform vertical thickness throughout. This base is of the usual wedge-shaped configuration in plan. The

base 1 is provided at the opposite sides of its median longitudinal dimension with air passages 2 which open at their ends at the ends of the base. Slots or openings 3 communicate with the upper portions of the passages 2, and also with the interior of the body of the iron. The passages 2 are'of greater transverse sectional area than the slots 3. The base 1 is provided at its oppo- Patented Oct. 27, 1914. Application filed March 25, 1913. Serial No. 756,657.

site sides and beyond the outer edges of the H slots 3, with pockets 4. These pockets may be of any desired number and any desired depth;

'Walls 5 rise from the edges of the base 1, and the inner surfaces of the said walls are at rightangles to the plane of the upper surface of the base 1. The space between the inner surfaces of the walls 5 and the upper surface of the base 1 constitutes a combustion chamber. The walls 5 are provided at their upper edges with recesses 6 through which the products of combustion may escape from the interior of the body of the iron.

The iron is provided with a cover 7 which in turn is provided with depending ears 8 which are located adjacent the inner surfaces of the rear portions of the side walls 5 of the iron. A pin 9 passes transversely through the side walls 5 of the iron andthe ears 8 and serves as means upon which the cover 7 may be swung to an open or closed position, with relation to the body of the iron. The pin 9 is provided with a slotted with the cover 7 in any desired manner.

A stud 12 is screw-threaded into engage-. ment with the upper forward portion of the body of the iron, and is adapted to be received in the notch 11 of the cover 7 when the said cover is in a closed position over the body 5 of the iron. The said stud 12 is pro vided with a handle portion 13 which is adapted to be swung over and in contact with the upper surface of the forward portion of the cover 7 when the said cover is closed, and thus hold the forward end of the cover in engagement with the forward portion of the body of the iron. Thecover? is provided at its under side and in the vicinity of its forward end with a lug 14 which is adapted to lie adjacent the inner surface of the forward end of the body of thefiron when the cover is closed so that the said cover is restrained against movement with relation to the body of theiron when the cover is closed, and the iron is being used.

A tube 15 passes through the rear wall 5 of the body of the iron and traverses the length of the said body and is spaced above the upper surface of the base 1. The forward end of the tube 15is screw-threaded as at 16 into vengagementwith the forward portion of the body of the iron. This screwthreaded engagement serves as the only means whereby the tube 15 is secured to the body of the iron, and the forward portion of the body of the iron serves as a closure for the forward end of the tube 15.- The tube 15 is provided at its lower portion and arranged in rows disposed at the opposite sides of the median longitudinal dimension of the tube with orifices 17 which are disposed downwardly and outwardly toward the upper ends of the slots 8. A flexible hose or tube (not shown) may be connected with the rear end of. the tube 15 in any desired manner.

In operation, the features of the iron have the following'functions. Gas is passed into the tube 15 and escapes therefrom into the combustion chamber of the base through the orifices 17. This gas is ignited at the lower.

outer ends of the said orifices and the flames sweep across the upper edges of the slots 8 and create a certain amount of suction draft through the passages 2 and the slots 3. In-

asmuch as the passages 2 are open at the forward and rear ends of the iron, the air will readily enter the said passages irrespective of the direction in which the iron is being moved during the ironing operation. The air thus admitted and mixed with the 'flames, promotes combustion in the combustion chamber, and consequently the gas is 1 body.

practically completely consumed, and the base 1 of the body is thoroughly and uniformly heated. As the flames sweep over the upper edges of the slots 3 thin films of air are swept over the intermediate upper surface portion of the base 1, and these films enter the pockets 4:. As the flames continue to move over the pockets toward the vertical inner surfaces of the side walls 5,the air which has accumulated in the pockets 4, is taken up by the flames, and thus the combustion is further perfected, with the result that an intense heatis attained by the use of a minimum supply of gas and a maximunifsupply of air. ,Theprod'ucts of combustion eventually ascend toward the upper edge portions of the walls 5, and pass out of the body through the recesses 6. When it is desired toclean theinterior of the body, the handle portion 13 of the stud 12 may be turned so that it is located over the notch 11 at the forward end of the cover: 7, and thus the cover may be swung back from over the After this has been done, any particles of carbon, soot, etc., which haveaccumulated in the body may be readily removed when the cover may be swung down to closed position and secured by turning the handle portion 18.. of the stud 12 rearwardly over a solid or closed portion of the said cover. It will therefore be seen that an iron of simple structure is provided, and that in operation the said iron may be effectually heated at the expenditure of a minimum quantity of gas, and that the parts are so assembled as to be readily accessible for cleaning and other purposes.

Having thus described the invention, what is claimed as new is:

1. An iron comprising a base having passages extending through the same between the upper and lower surfaces thereof, said base having slots which extend down from the upper surface of the base into the passages, said passages extending from end to end of the base and located at opposite sides of the median longitudinal dimension of the base, edge walls ascending from the base, a cover for the base and a tube leading into the base and having orifices directed toward the upper endsof said slots.

2. An iron comprising a base havingpassages located between the upper and lower surfaces thereof, and opening at their ends at the ends of the base, said base having slots which extend down from the upper surface of the base into the passages, the passages being of" greater transverse sectional area than the slots, edge wallsrising from the base, a tube located above the base and having orifices disposed toward the upper edges of the slots and a cover for the base.

sages located between its upper and lower surfaces and having slots leading from the upper surface into the passages, Walls rising from the edges of the base. said base having between the slots and the walls, pockets, a tube located above the base and having orifices directed toward the slots, and a cover for the base.

4. An iron comprising a base having passages located between its upper and lower surfaces, and open at their ends at the ends of the base, said passages being located at the opposite sides of the median longitudinal dimension of the base, walls rising from the base, said base having pockets lo cated between the walls and the slots, a tube located over the median longitudinal dimension of the base and spaced from the base, said tube having at its lower portion orifices directed toward the upper edges of the slots, and a cover for the base.

In testimony whereof I aflix my signature in presence of two witnesses.
